Those subs are pretty efficient...with that amp they will work great. Make sure to get the impedance of the sub to match your amp for max ouput from the amp.

You'll be surprised by the outout from a couple 15 dollar drivers...I have a couple of the EHQS 12's....to me they are great woofers...best you can get for 25 dollars...very efficient and can get fairly loud in a big ported box
